NlTED STATES AMANT H. OHMANN-DUMESNIL, OF ST. LOUIS, MISSOURI.

SSTAIR-CARPET FASTENER.

SPECIFICATION forming part of Letters Patent No. 249,976, dated November 22, 1881.

(Model.)

To all whom it may concern:

Be it known that I, AMANT H. OI-IMANN-DU- MESNIL, of St. Louis, in the State of Missouri, have invented a new and Improved Stair-Garpet Holder, of which the following is a specification.

The object of my invention is to provide a new and improved device for holding stair-carpet in such a manner that it can be removed or replaced and fastened conveniently and rapidly.

The invention consists of a latch provided 011 its under side with one or more studs or pins, which latch is pivoted to a prismatical or beveled plate or block which is secured to the riser and tread at the angle formed by the same, the carpet being placed over this block and held in place by the latch, which is closed down upon the block, the pins passing through the carpetinto apertures in the block, the latch being locked by a spring-or a pivoted catch.

Reference is to be had to the accompanying drawings, forming part of this specification,in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view ofsteps on which thecarpetis held by means ofrnyimproved staircarpet holder. Fig. 2 is a plan view of my improved stair-carpet holder with a locking-catch, the catch being closed. Fig. 3 is a plan view ofthe same, showing the latch raised and parts in section. Fig. 4 is a cross-sectional elevation of the same on the line or :r, Fig. 2. Fig. 5 is a plan view of a modification of my improved stair-carpet holder, thelatch beingclosed. Fig. 6 isa plan view of the same, showing the latch raised and parts in section. Fig. 7 is a crosssectional elevation of the same on the line yy, Fig. 5. Fig. 8 is a longitudinal sectional elevation of the same.

A latch or plate, A, provided with one or more studs or pins, B, on the under side, is pivoted to a prismatical or beveled block or plate, (3, which is fastened to the riser D and the tread or step E at the angle formed by the same. The block or plate 0 is preferably fastened by means of one or more screws, but can be fastened by means.of studs projecting from the inner surface of this block and driven into the o riser and tread, or by means of any other suitable devices. The studs B (providing there are more than one) maybe arranged longitudinally, as'shown in Fig. 2, or transversely at the end of the latch A, as shown in Fig. 5.

The block 0 may be provided with a longitudinal spring, F, against the free end of which the squared or angular end of the latch Arests; or the block 0 may be provided at the end at which the latch is pivoted to it with a transversely-swinging pivoted latch or catch, G, or with any suitable devices for locking the latch A in position. The spring F holds the latch A in the raised or closed position, and likewise the catch G, when closed, prevents a movement of the latch A from the raised to the closed position, or vice versa. The block 0 is provided with recesses or apertures H, to receive the ends of the pins or studs B when the latch is closed.

If desired, the lower or inner surface of the latch may be serrated or provided with a serrated ridge, J, for the purpose of assisting in holding the carpet.

One of my improved stair-carpet holders is fastened to each tread and corresponding riser, at each end of the same, the carpet-holders bein g separated a distance equal to the width of the stair-carpet K.

The operation is as follows: The latches A are raised, as shown in Figs. 3 and 6, and the carpet K is placed on the stairs, the carpet passing over the upper surface of the blocks 0. V hen the carpet is in the desired position the latches Aare closed down, the studs or pins B piercing or passing through the carpet, as shown in Figs. 1, 4, and 7. If the blocks O are provided with the springs F, they will hold the latches in the closed position, and if the blocks are provided with the catches G, these catches must first be opened before the latches can be closed, and then the catches G are closed to lock the latches A in position. The carpet is thus held firmly, and if it is to be removed the latches A need only be raised, thus permitting the carpet to be removed and replaced and fastened very rapidly and conveniently.

Thelatches Amay be ornamented and plated. These holders may also be used for narrow hall-carpets if the block 0 is made flat.

Having thus fully-described my invention,

3. In a stair-carpet holder, the combination, with the block 0, of the latch A, pivoted thereto and provided with studs B and a serrated ridge, and of the spring F, substantially as herein shown and described, and for the purpose set forth.
